What is the main content of the essay "Jie Jiang under torture"

In the 1940s, with the destruction of the underground party in Chongqing, the revolutionary struggle situation became more and more severe. Peng Yongwu, the leader of Chongqing underground party, began to arouse the suspicion of the enemy because of his "single" status. So, the girl named "Jiang Jie" was ordered to pretend to be husband and wife and work underground. Although it was difficult for Jiang Zhujun to accept the task emotionally, she accepted it for the sake of Peng Yongwu's security and revolutionary cause.

Short essays are not literary genres, so there was no such thing as short essays before. In recent years, due to the rapid development of society and the accelerated pace of people's life, there is a great demand for short essays. Therefore, the essay has been raised to a new height and entered people's field of vision. Modern literature can be divided into novel, drama, poetry and prose (prose here refers to prose in a broad sense). After the length of each kind of work is compressed, it becomes a short article. However, due to its own characteristics and social needs, there are relatively few drama sketches. So the essay mainly covers novels, poems and essays. Narrative, expository, expository, essay and other literary genres and practical writing genres such as reports, advertisements and summaries all belong to the category of big prose, so they are also covered by short essays. In short, as long as the length is short enough, it is a short essay.
